Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (ufs, lpfc, qla2xxx, mpi3mr, libsas).

  The major update (which causes a conflict with block, see below) is
  Christoph removing the queue limits and their associated block
  helpers.

  The remaining patches are assorted minor fixes and deprecated function
  updates plus a bit of constification"
